Abstract

A patient warming blanket comprising at least two layers capable of forming a hollow air space between the two layers for receiving warm air from a heating unit via an inlet port at or near an end of the blanket. The two layers being arranged so that the hollow air space forms at least one tubular portion disposed longitudinally there within, and one of the two layers has at least a portion of its surface formed of porous material so that warmed air is delivered to said patient by diffusion through said porous material. The tubular portion has non- parallel sides such that the sides of the tubular portion are further apart from each other at a first end of the tubular portion closer to the inlet port than at a second end of the tubular portion remote from the inlet port.

Claims (19)

1. A patient warming blanket comprising at least two layers capable of forming a hollow air space between said two layers for receiving warm air from a heating unit via an inlet port at or near an end of said blanket, said two layers being arranged so that said hollow air space forms at least one tubular portion disposed longitudinally within said blanket, and one of said two layers has at least a portion of its surface formed of porous material so that warmed air is delivered to said patient by diffusion through said porous material, wherein said tubular portion has non- parallel sides such that said sides of said tubular portion are further apart from each other at a first end of said tubular portion closer to said inlet port than at a second end of said tubular portion remote from said inlet port.
2. A patient warming blanket as claimed in claim 1, wherein said at least one tubular portion comprises a plurality of tubular portions fluidally in communication with each other.
3. A patient warming blanket as claimed in claim 2, wherein said plurality of tubular portions are disposed longitudinally adjacent to each other, and a manifold is disposed between said inlet port and said first ends of said tubular portions.
4. A patient warming blanket as claimed in claim 3 wherein said manifold has a length which is no less than twenty percent the total length of said blanket.
5. A patient warming blanket as claimed in any of claims 3 or 4, wherein said first ends of said tubular portions are staggered relative to each other.
6. A patient warming blanket as claimed in claim 5, wherein said staggered first ends of said tubular portions are staggered such that centrally disposed tubular portions have first ends longitudinally further away from said inlet port than adjacent tubular portions disposed on either side thereof.
7. A patient warming blanket as claimed in claim 3, wherein a gallery is disposed at a bottom end of said blanket near said second ends of said tubular portions and said gallery is in fluid communication with said gallery, and said gallery has a width between said bottom end and said second ends of said tubular portions which is no less than ten percent the total length of said blanket.
8. A patient warming blanket as claimed in claim 1, wherein at least one of the outermost tubular portions is about ten percent larger than an adjacent tubular portion.
9. A patient warming blanket as claimed in claim 1, wherein said two layers are welded together such that said hollow space is substantially surrounded by a peripheral weld.
10. A patient warming blanket as claimed in claim 9, wherein an external weld substantially surrounds said peripheral weld.
11. A patient warming blanket comprising at least two layers capable of forming a hollow air space between said two layers for receiving warm air from a heating unit via an inlet port at or near an end of said blanket, said two layers being arranged so that said hollow air space comprises a plurality of adjacent tubular portions disposed longitudinally within said blanket and fluidally in communication with each other via a manifold at said first ends of said tubular portions near said inlet port and a gallery at the opposed ends of said tubular portions, and one of said two layers has at least a portion of its surface formed of porous material so that warmed air is delivered to said patient by diffusion through said porous material, wherein said tubular portions have non- parallel sides such that said sides of said tubular portions are further apart from each other at their first ends nearer to said inlet port than at said opposed ends of said tubular portion near said gallery.
12. A patient warming blanket as claimed in claim 11 wherein said manifold has a length which is no less than twenty percent the total length of said blanket.
13. A patient warming blanket as claimed in claim 12, wherein said first ends of said tubular portions are staggered relative to each other such that centrally disposed tubular portions have first ends longitudinally further away from said inlet port than adjacent tubular portions disposed on either side thereof.
14. A patient warming blanket as claimed in claim 11, wherein said gallery has a width between said bottom end of said blanket and said opposed ends of said tubular portions which is no less than ten percent the total length of said blanket.
15. A patient warming blanket as claimed in claim 11, wherein at least one of the outermost tubular portions is about ten percent larger than an adjacent tubular portion.
16. A patient warming blanket as claimed in claim 11, wherein said two layers are welded together such that said hollow space is substantially surrounded by a peripheral weld.
17. A patient warming blanket as claimed in claim 16, wherein an external weld substantially surrounds said peripheral weld.
18. A patient warming blanket comprising at least two layers capable of forming a hollow air space between said two layers for receiving warm air from a heating unit via an inlet port at or near an end of said blanket, said two layers being arranged so that said hollow air space is U-shaped and comprising first and second elongate tubular portions fluidally connected by a tubular bend portion, and one of said two layers has at least a portion of its surface formed of porous material so that warmed air is delivered to said patient by diffusion through said porous material, said first elongate tubular portion having an inlet and associated manifold at its free end, wherein said first tubular portion has non- parallel sides such that said sides of said first tubular portion are further apart from each other at a first end of said tubular portion closer to said inlet port than at a second end of said tubular portion near said tubular bend.
19. A patient warming blanket as claimed in claim 18, wherein said second tubular portion has non- parallel sides such that said sides of said second tubular portion are further closer together at an end of said second tubular portion closer to said tubular bend portion than at a second end of said second tubular portion near its closed free end.
